WALL(1) USER COMMANDS WALL(1) NAME wall - write to all users logged in SYNOPSIS wall [ -a ] [ filename ] DESCRIPTION wall reads the standard input until an EOF. It then sends this message, preceded by `Broadcast Message ...', to all logged in users. If filename is given, then the message is read in from that file. Normally, pseudo-terminals that do not correspond to rlogin sessions are ignored. Thus when in sunview(1), the message appears only on the console window.
